TUBNSTILE.

Specification of Letters Patent.-

Patented June9, 1914.

Application filed October 8, 1912. Serial No. 724,503.

To all whom it may concern Be it known that ll, Lnorom) W. Lorin- Brno, a citizen of the United States, and a resident of San Antonio, in the county of lexar and State of. Texas, have made certain new and useful Improvements 1n Turnstiles, of which the following is a specifieation.

My invention relates to turnstiles for general use, and more particularly to a type of turnstile especially adapted for use in so called pay-as-you-enter cars.

Reference is made to the accompanying drawings forminga part of this specification and in which like letters indicate like parts.

Figure 1 is a fragmentary perspective view showing the vestibule of a street car equipped with my device. Fig. 2 is a hori zontal section through the turnstile and parts immediately associated therewith. Fig. 3 is a detail showing in section the principal mechanism of the turnstile. Fig. 4 is a perspective showing the cam plate forming a part of the turnstile and used for swinging the arms thereof into and out of a predetermined plane of rotation. Fig. 5 is a view partly an inverted plan and partly a section showing certain parts of the apparatus located near the car ceiling, 1

The ceiling of thecar-is shown at 6 an the floor at 7. The end wall of the car is shown at 8 and extends from the floor to the ceiling. The end wall, the portion of the ceiling adjacent thereto and the adjacent portion of the car floor together form a simple inclosure or vestibule. ht 910 are the car doors through which the passengers enter and leave the car. At ll-l2 u re two stationary posts. The post 12 at its top end branches into two members 13 which are secured to the ceiling hy aid of ceiling plates 14:. These posts may be conveniently made of piping.

The hand rail 15 is secured at one of its ends to the post 12. This hand rail is provided with a portion -l6 extending toward the door 9 and with a portion 17 extending from the portion last mentioned to the floor. -ecured upon the ceiling 6 is a ceiling plate l8 which serves as a bearing. Mating this hearing is a floor plate 19 secured to the floor at a point directly under the ceiling plate 13. .t tubular sleeve 20 extends downwardly from the ceiling plate 13 and is in vertical alinement with another tubular sleeve 21. The sleeve last mentioned is stationary, whereas the sleeve 20 is revoluble. Extending through both of these sleeves is a'stationary post 22 reaching from the floor to the ceiling of the car and serving as a longitudinal bearing upon which the sleeve 20 is free to rotate, as will be understood from Fig. 3.

The cam plate 23 is mounted upon the upper end of the sleeve 21 and is provided with sloping portions 242 l. This cam plate is secured in position upon the sleeve 21 by aid of a set screw 25. The cam plate is provided with a bearing 26 of substantially annular form as shown. A. spring pawl 27 having substantially a .l-shape is sunken into the cam plate 23 and extends slightly into the opening of the bearing. This'opening is slightly enlarged at 28 for the purpose of allowing the adjacent end of the spring pawl 27 to have a little play. A ratchet pinion 28 is secured rigidly upon the revoluble sleeve: 20 and is engaged by the adjacent free end of the spring pawl.

ny this arrangementthe sleeve 20 is adapted to turn in one direction but is prevented; by the pawl from turning in the opposite direction. The pinion 28 is provided with an annular head 27 integral with it and is further provided with an annular head 29 also integral with it, but of greater gen eral diameter than the pinion. The annular head 29 rests upon the adjacent surface of the cam plate 23 and supports the'weight of the sleeve 20 and parts carried thereby.

.[i spider 30 encircles the sleeve 20 and is secured rigidly to the same. A number of arms 31 are severally. mounted upon stems 32, the latter being connected with the spider 30 by pivot pins 33. Rollers 34% encircle the stems 32 and are adapted toengage the cam plate 23. The rollers are in this instance shown as smooth, but T do not limit myself to this precise construction.

A shield 35 having generally the form of a cup is provided with slots 36 and is mounted rigidly upon the sleeve 20 by aid of a screw 37. The slots 36 are in alinement with the arms 31 and these arms when raised are adapted to extend radially outward through the slots as indicated in Flg. 1. When the arms hang vertically downward as indicated in Fig. 3, their upper ends and parts immediately adjacent thereto are completely hidden by the shield 35. The upper end of the sleeve 20 carries a 43 covered with rubber or other resilientsecured to the car ceiling and carrying a pivot pin t1 upon which the lever 39 is journaled. A spring 12 is secured to the lever 39 and to thecar ceiling for the purpose of retracting the lever39. A stop pin material is mounted partiallyfwithin the path of movement of the lever 39 and prevents excessive movement thereof in one direction. A cord 4:51 is connected at one of its ends to the lever39 and at its opposite end is secured to the actuating arm 150f a register a6. Another cord 47 is connr led with the actuating arm and extends to the opposite end ofithe car where all of the apparatus except the register 16 is duplicated.

I provide the casing 48 (see Fig. 5)., which is detachably-s'ecured upon the sleeve 6 in order to conceal and protect the spider 38, lever 39 and parts immediately associated therewith. 'This casing prevents 'the en trance of dust and dirt and also improves the appearance of the exposed parts.

The operation of my device is as follows:

The parts being assembled and arranged as above indicated," the conductor takes up his position behind the hand rail 15 and the apparatus is ready for use. Each passenger entering the car pushes one of the arms 31 angularly around for a distance representing one-quarter of a revolution, the passenger then entering the car through the door 9. The arm 31 thus pushed around by the passenger next swings downwardly owing to the fact that. its roller passes obliquely downward in engagement with the oblique face 24 of the cam plate 23. The next successive passenger performs the same operation by pushing against the next successive arm 31. As each arm in succession reachesthe obli ue portion 24 .of the cam plate, the arm ri es gradually upward until it reaches a horizontal position. The passengers are prevented from entering the door 10 by the adJacent arm 31 extending directly toward the post 11. The number of arms remaining extended at a particular instant is governed by the. proportions of the cam plate 23. In'this particular instance I show two arms as always extended, but I do not limit myself to this precise number. Nor do I limit myself to the precise construction herein shown, the scope of my invention. being commensurate with my claim.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is as follows:

A device of the character described comprising a tubular sleeve secured fixedly in position, .a cam plate mounted rigidly upon said tubular sleeve and provided with a bearing of substantially annular form, a spider disposed adjacent said cam plate,'-a

revolublesleeve secured to said spider and extending into said bearing of said cam plate, a rod'extending through said tubular sleeve and said revoluble sleeve, an annular head secured to said revoluble sleeve and carrying a pinion, a spring pawl mounted upon said cam plate and engaging said pinion for the purpose of preventing said spider from turningv in one direction, and a plurality of arms pivotall connected with said spider for turning t e same in one direct-ion, each of said arms bein provided with a portion for engaging sai cam plate for the purpose ofguiding said arm-into different planes as said arms arejturned, so as to actuate said revoluble sleeve.
